Haven't been to Disney world in years. There will be 7 of us including 3 small grandchildren (3, 5 & 7). We will be making 3 dining reservations (chef Mickeys, Cinderella's and Hollywood and Vine). Otherwise we don't want to be restricted to a particular dining schedule (ie - reservations) for lunch or dinner. Are we making a mistake thinking that we can "wing it" or should we make a reservation for each night and put up with the restrictions that come with a set schedule.
